The Mercedes duo of Nico Rosberg and Lewis Hamilton finished on top of the time sheets for the first free practice session for the Brazilian Grand Prix.

Nico Rosberg finished in P1 with a time of 1:24.781. His team mate Lewis Hamilton finished in P2 with a 1:25.230, 0.449s off the pace of his team mate. Red Bull’s Sebastian Vettel finished P3 with a time of 1:25.387 and McLaren’s Jenson Button in P4 with a time of 1:25.593. Ferrari’s Fernando Alonso ended the session in P5.

With the track damp and slippery it made it nearly impossible for teams to test the new Pirelli tyre compounds for next season but that did not stop Vettel venturing out on track for two laps with them in order to obtain some data about them.

Young Daniil Kvyat was particularly impressive in the wet, finishing the session in P8 with the Toro Rosso in only his second outing for the Faenza based team.
